Radio and TV Interference
The LRA2900A Series generates and uses radio frequency energy, and if not installed and used properly—that
is, in strict accordance with the manufacturer's instructions—may cause interference to radio and television
reception. The LRA2900A Series has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection from such interference in a commercial installation. However, there is no guarantee
that interference will not occur in a particular installation. If the LRA2900A Series causes interference to radio
or television reception, which can be determined by disconnecting the cables, try to correct the interference by
one or more of the following measures: moving the computing equipment away from the receiver, re-orienting
the receiving antenna, and/or plugging the receiving equipment into a different AC outlet (such that the computing equipment and receiver are on different branches)
This device is not intended to be connected to the public telephone network in Europe.

Industry Canada Radio Frequency Interference Statements
This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the
Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils
numériques de la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.
Industry Canada Notice
The Canadian Department of Communications label identifies certified equipment. This certification means
that the equipment meets certain telecommunications network protective, operational and safety requirements. The Department does not guarantee the equipment will operate to the user's satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The customer should be
aware that compliance with the above condition may not prevent degradation of service in some situations.
Repairs to some certified equipment should be made by an authorized maintenance facility designated by the
supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the user to disconnect the equipment. Users should ensure
for their own protection that the ground connections of the power utility, telephone lines and internal metallic
water pipe system, are connected together. This protection may be particularly important in rural areas
Users should not attempt to make such connections themselves,
but should contact appropriate electric inspection authority, or
electrician, as appropriate.
FCC Compliance
The LRA2900A has been tested and found to comply with the specifications found in Part 68 of the FCC rules and
regulations. A label on the equipment bears the FCC registration number. You may be requested to provide this
information to your telephone company. The telephone company may decide to temporarily dicontinue your service
if they believe that the LRA2900A may cause harm to the telephone network. Whenever possible the telephone
company will attempt to notify you in advance. You have a right, if you choose, to file a complaint with the FCC.
FCC Information
The LRA2900A Series has been tested and registered in compliance with the specifications in Part 68 of the

Model LRA2900A RAS Getting Started Guide
Model LRA2900A Remote Access Server overview
The Model LRA2900A is a central site remote access server with integrated modems which terminate dial-up
analog and digital users. The Model LRA2900A RAS combines up to 120 analog and digital modems, RAS
software, a 10/100 Ethernet port, IP Routing, Frame Relay/PPP forwarding, and four T1/E1 WAN ports.
The LRA2900A RAS simultaneously consolidates analog modem and digital ISDN remote access connections
(over PSTN digital trunks) using a completely digital approach. Up to four T1/E1/PRI ports provide PSTN
and/or PABX connectivity and terminate up to 120 analog modem or digital ISDN calls within a single chassis. The Model LRA2900A incorporates channel bank, terminal server, router and modem functionality in a
self-contained, compact package.

Hardware overview
The Model LRA2900A RAS is a fully integrated remote access server for central site concentration of analog
and digital modem calls. The RAS (see figure 2) comprises a 1U-high 17-inch wide chassis that contains a
motherboard and two dual-redundant power supplies. A full set of LEDs are present on the chassis front panel,
while connections for WAN, LAN, and control ports are present on the rear of the chassis. Two IEC-320
receptacles provide for AC power input. Optional DC power supplies with 32 to 72 VDC are available.
Figure 2. Model LRA2900A RAS features
